## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Supply Chain Security**: 97/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it.
  - 3 of 3 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 23/100
  - Repository check failed: the declared repository URL redirects; it must resolve directly.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 30 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 528 tokens (~40/item across 13 items; 13 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (23% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (13)

### `retain` (~83 tokens)

Screen and store a durable memory. The quarantine gate runs on
every write — entries flagged secret:/injection:/limit:/shape:
land in quarantine, never in recall. Returns the stored entry.

Input parameters:

- `content` (string, required)
- `source_rowid`
- `source_session` (string)
- `tags` (string)
- `workspace` (string)

### `recall` (~48 tokens)

Keyword-ranked recall over active memories only — quarantined
and retracted entries never leak into context.

Input parameters:

- `limit` (integer)
- `query` (string)
- `tags` (string)

Output parameters:

- `result` (array)

### `screen` (~48 tokens)

Dry-run the anti-poisoning gate: returns the status retain
would produce (active | quarantined + reasons) without writing.

Input parameters:

- `content` (string, required)
- `tags` (string)

### `list` (~40 tokens)

List memory entries, optionally by status (active, proposed,
quarantined, retracted).

Input parameters:

- `limit` (integer)
- `status` (string)

Output parameters:

- `result` (array)

### `retract` (~27 tokens)

Withdraw an entry — kept for history, never recalled again.

Input parameters:

- `entry_id` (integer, required)

### `supersede` (~41 tokens)

Replace an entry with a corrected version (versioned).

Input parameters:

- `content` (string, required)
- `entry_id` (integer, required)
- `tags` (string)

### `quarantine` (~33 tokens)

Move an entry to the quarantine lane (review hold).

Input parameters:

- `entry_id` (integer, required)
- `reason` (string)

### `release` (~27 tokens)

Human override: move a quarantined entry back to active.

Input parameters:

- `entry_id` (integer, required)

### `approve` (~23 tokens)

Promote a proposed extraction to active memory.

Input parameters:

- `entry_id` (integer, required)

### `conflicts` (~19 tokens)

Contradiction pairs linked at retain time (both kept).

Output parameters:

- `result` (array)

### `prime` (~43 tokens)

Compact recalled-context block for a workspace — global plus
workspace-scoped active memories, token-bounded.

Input parameters:

- `max_tokens` (integer)
- `workspace` (string)

### `verify` (~37 tokens)

Audit an entry's provenance against a Devin sessions.db
(read-only).

Input parameters:

- `entry_id` (integer, required)
- `sessions_db` (string, required)

### `extract` (~59 tokens)

Mine a Devin session (read-only sessions.db) for durable
knowledge -> proposed entries awaiting approve.

Input parameters:

- `auto_approve` (boolean)
- `latest` (boolean)
- `session_id` (string)
- `sessions_db` (string, required)

io.github.Icaro0310/devin-memory is an MCP server listed in the public MCP registry as io.github.Icaro0310/devin-memory. Anti-poisoning memory for agents: provenance, conflicts, quarantine gate. This page covers its PyPI package (devin-memory-mcp).

### Is the io.github.Icaro0310/devin-memory MCP server safe to use?

io.github.Icaro0310/devin-memory scores 75 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.Icaro0310/devin-memory MCP server expose?

io.github.Icaro0310/devin-memory exposes 13 tools: retain, recall, screen, list, retract, and 8 more. Their descriptions and schemas cost roughly 528 tokens of context every time the server is loaded.

### Is the io.github.Icaro0310/devin-memory MCP server still maintained?

io.github.Icaro0310/devin-memory is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the io.github.Icaro0310/devin-memory MCP server under?

io.github.Icaro0310/devin-memory declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
